J.,assignor to American Car and Foundry Company, New York, N. Y., acorporation of New Jersey Application January 27, 1933.' Serial No.653,850 12 claims. (o1. 10a-364) This invention relates to mine cars andhas for one object the provision of a n ew and improved mine car oflarge lading capacity in which the body is supported by stub axles. x

Another object of this invention is the provision of a mine car having anew and improved combined stub axle and wheel hood assembly.

Other objects and advantages of this invention will be apparent from thefollowing description taken in conjunction'- with the accompanyingdrawings in which:

Figure 1 is a side elevation the present invention.

Fig. 2 is a sectional view on the line 2-2, Fig. 1. Fig. 3 is asectional view on the line 3-3, Fig. 1. Fig. 4 is a sectional view onthe line 4--4, Fig. 3. Fig. 5 is a sectional view on the line 5-5, Fig.3. Fig. 6 is a sectional view through the side floor portion of a carshowing a modied form vof the 2 0 invention.

of the mine car of Fig. 7 is a side elevation view of the constructionshown in Fig. 6, and

Fig. 8 isa top plan view of the construction shown in Figs. 6 and 7.

Referring now more particularly to the drawings in which similarcharacters of reference designate similar parts in the several views,the mine car of the present invention comprises abody indicatedgenerally at A having side walls 2, a fixed end wall 4, and an end gate6, the latter being provided with a bail 7. While the drawings show anend dump mine car, it will be apparent' from the description that withinthe spirit of the invention both ends of the car body may be providedwith fixed endy walls to provide a rotary dump car if desired.

'Ihe body includes a bottom indicated generally at B and comprises acentral floor portion 8 se.- cured to or formed integral with the bodyside sills. In the instance shown, the side sills are indicatedgenerally at S and comprise upwardly and then outwardly extendingflanges 10 and 12 respectively of the side edge portions of thecentralfloor 8. If desired, independent members such as rolled Z-sections,channels, angles or the like, or suitable plate metal members may beutilized to form the side sills.

The car body also includes two main oppositely arranged side sectionsIbut inasmuch as they are 00 identical only one thereof is shown. Theside section is shown clearly in Fig. 3 and is shaped by a bendingoperation to provide a side door portion 14 and the side wall 2 integralwith said portion 14, the section being secured as byrivets 16 f to theupper flange 12 of the side sill and being provided withwheel receivingopenings 18. The

upper edge portions of the side and end walls are stiiened in anysuitable manner as by an inturned bead 20 and the entire body isreinforced by belts 22 secured to the sidewalls -and extending under thebody from side to side; the belts tral iioor portion and lying againstthe side sills. The belts 22are secured to the car body by suitablefasteners such as the rivets 24. y

The Wheels are indicated at 26 and they carry stub axles 28 mounted inoppositely arranged outer and inner bearing members 30 and 32respectively, bearing 30 comprising a. socket 34 formed with a bracket36 secured to a support 38 depending from the side floor portion 14 (seeFig. 3). Bearing member 32 comprises a pedestal 40 formed integral witha bracket `42 having oppo- 'sitely directed arms 44 which are of alength sufcient to extend between adjacent straps 22.A A pin 46 extendsbetween the pedestal jaws for an obvious purpose, as clearly shown inFigs. 2 and 5.

To close thev openings 18 and to cover the wheels 26, wheel housingsindicated generally at H are provided, each of which comprises a metal lextending from the side floor portions and cen.

pressing formed to. provide a hood portion 48 having a marginalattaching flange 50 extending completely therearound and of such adimension as to underlie-the side floor' portion completely aroundtheopening 18 (see Fig. 2), and to extend between and to underlie adjacentvbelts .22, as

shown in Figs. 4 and 5. In practice the end portions of the marginalflange 50 are interposed between the belts 22 and the arms 44 of thebearing member 32 and the rivets which connect the arms 44 to the carbody also serve to secure the wheel housings H. l I r The iiange 50 atits sides is formed with depending attaching iianges or extensions 54and 56 arranged respectively between bearing member 30 and support 38and between bearing member 32 are then inserted through the wheelyopenings 18.

The bearings 30 and 32 are then applied in position and secured,together with the wheel'hood, to their respective supportsthe support 38and the Side. .S..1 1 E. `This being done, the; stub axle with itsassociated wheel 26 may then be easily inserted into the bearings 30 and32 and secured against displacement by the pin 46. The constructionherein provides a strong and durable mine car which is formed of fewparts and is easy and inexpensive to manufacture. It is apparent thatthe wheels 26 may be easily and quicki-v ly removed from theirsupporting bearings 30 and 32 for replacement or repair.

Figs. 6, f7 and 8 show a modied form of the invention and moreparticularly disclose a form of car at the wheel housing portion. Thewheels 26 carry stub axles 28 which are mounted in inner and outerpedestal members. To distinguish the construction in Figs. 6, 7 and 8from the remaining figures in the drawings the pedestal members areindicated at 60 and 62 respectively andare substantially identical, eachhaving legs 64 which dene therebetween a jaw 66 which receives the axle28. Tie bars 68 are provided for an obvious purpose.

The wheel housing in Figs. 6, 7 and 8 is indicated at '70 and issubstantially rectangular in plan, being provided with a marginalattaching flange 72 which, along one side portion of the housing,extends under the side sill S and is provided with a depending attachingflange 74 interposed between the inner pedestal members 60 and the sidesill. Suitable fasteners 76 secure the pedestal 60, side sill S and ange'74 together as clearly shown in Fig. 6.' The opposite portion of iiange72 underlies the side floor portion B of the car bottom (shown in brokenlines in Fig. 6) and rests upon the horizontal portion 78 ofan internalwheel housing brace member indicated generally at 80 provided with avertically arranged web portion .82 which extends to the upper portionof the wheel housing and has its upper edge portion welded to saidhousing as shown at 84. The side edge portions of the web.82 are flangedoutwardly as shown at 86 and are united with the upwardly sloping outerwall 88 of the wheel housing 70 by being welded thereto as shown at 89.The horizontal leg 78 of the brace member 80 is supported on thedownwardly oiset portion 90 of a channel-shaped side floor portionsupporting member 92. The portion 90 of the channel member 92 isdownwardly offset a distance sufficient to permit the marginal flange 72of the wheel housing '70 to be in substantially the same horizontalplane as the web of the channel member 92, as shown clearly in Fig. 6,the channel member 92 being attached to the side floor portion B and thelatter overlapping the marginal iange 72 as shown in brokenlines in Fig.6. If desired, the rivets 76 may be eliminated and connection of thepedestal 60, ilange 74 and sill S be made by welding. It

` is also apparent that while other rivets or fasteners may be used toconnect the side oor portion B and channel member 92, these elements maybe connected, if desired, by welding. The member 92 serves as a supportfor the outer pedestal member 62 and the latter may be secured inposition in any suitable manner as by being Welded to said member 92. Inthe construction shown in Figs. 6, 7 and 8 it is apparent that theseveral parts may be connected together by welding and that the wheelhousing 70 is braced by the member 80. It will also be apparent thattheside oor portions B are stiiened and reinforced by the member 92 andthe connection between the wheel housing 70, brace member 80, andchannel member 92 is such as to stiften the car at this particular zone.Due to the fact that the members 60 and 62 are pedestal members i't willbe apparent that upon removal of the tie bars 68 the body may be liftedto remove the wheel 26 and axle 28 as an` assembled the presentinvention will be fully apparent to i those skilled in the art but it isto be understoodthat the drawings herein are for illustrative pur.

poses only and various changes in the form and proportions of theconstruction may be made within the scope of the appended claims withoutdeparting from the spirit of the invention.
